Complete mitochondrial genome and the phylogenetic position of theTaiwan spurdog shark Squalus formosus (Squaliformes: Squalidae).

ABSTRACT: The complete mitogenome of the Taiwan spurdog shark Squalus formosus (Squaliformes: Squalidae) is determined in this study. It is a circle molecular (16,735?bp), containing 37 genes with typical order to that of most other vertebrates. The nucleotide composition is: A 30.9%; C 24.5%; G 14.2%; T 30.5%. Two start codons (GTG and ATG) and two stop codons (TAG and TAA/T) are used in the protein-coding genes. 22 tRNA genes range from 66?bp (tRNA-Ser2) to 75?bp (tRNA-Leu1). The phylogenetic result shows that S. formosus clusters to the (Squalus acanthias?+?Cirrhigaleus australis) clade.

Complete mitochondrial genome and phylogenetic position of Chaenodraco wilsoni.

Project description:Chaenodraco wilsoni, a species of Channichthyidae, inhabits in southern ocean. The total length of complete mitochondrial genome of C. wilsoni is 17,432?bp, which encoded 37 genes. Similar to most Antarctic fishes, the ND6/tRNA (glu) translocation and an additional non-coding region linked with ND6 have also occurred in C. wilsoni. The ML tree supports that C. wilsoni has closer relationship with Chionodraco species. Our research will provide more molecular biology information about C. wilsoni and deepen the understanding of Antarctic fishes.

The complete mitochondrial genome of Aquila nipalensis and its phylogenetic position.

Project description:Mitochondrial genome sequences are valuable resources for systematics and conservation biology studies. In this paper, we present the complete mitogenome of Aquila nipalensis which was 18,450?bp in length. The gene content and arrangement were typical for avian mtDNA. The overall A?+?T content of was 54.1%, and the AT skew was calculated as 0.12 for the complete mitogenome of A. nipalensis. The maximum-likelihood (ML) tree based on the concatenated 12 protein-coding genes (PCGs) revealed the basal phylogenetic position of A. nipalensis in Aquila.

Complete mitochondrial genome and phylogenetic analysis of the copper shark Carcharhinus brachyurus (Gunther, 1870).

Project description:Copper shark (Carcharhinus brachyurus Günther, 1870) is one of the most widely distributed but least known species in the family Carcharhinidae. Herein, we report the first complete mitogenome of C. brachyurus. The overall structure of the 16,704 bp C. brachyurus mitogenome was similar to that of other Carcharhinus species and showed the highest average nucleotide identity (97.1%) with the spinner shark (Carcharhinus brevipinna). Multigene phylogeny using 13 protein-coding genes (PCGs) in the mitogenome resolved C. brachyurus clustered with other species within the genus; the overall tree topology was congruent with recent phylogenetic studies of this species. These results provide important information for conservation genetics and further evolutionary studies of sharks.
